SPECIFICATION formingpart of Letters Patent No. 766,949, dated August 9,1904.

Application filed March 14, 1903. Serial No. 147,788. (No model.)

ing is a specification.

My invention relates more particularly to the line-spacing mechanism oftype-writing machines; and it aimsto utilize the return or movement ofthe carriage from left to right to automatically space the platen orpaper-cylinder. It also aims to provide means whereby the degree ofmovement of the platen may be varied to conform to the spacing desired.

To these and other ends the invention consists in the improvementshereinafter described and claimed.

The nature, characteristic features, and scope of the invention will bemore clearly understood from the following detailed description, takenin connection with the accompanying drawings, forming a part hereof,wherein- Figure l is a perspective view of line-spac- -ing mechanismembodying features of the invention. Fig. 2 is a top view of the guide,and Fig. 3 is a sectional view of the same.

Referring to the drawings, A represents the paper cylinder carriageprovided with a bracket B, which aifords a bearing for one end of thepaper-cylinder 0r platen O. The axle of said cylinder carries the usualratchetwheel D, and between said wheel and the bracket a double-armedlever E is also mounted in relation to the aXle O. The upper part or armof said lever carries a pawl F, that is held in engagement with theteeth of the ratchet-wheel through the medium of a spring G. The otherarm of said lever penetrates a slot or opening b of the bracket and isprovided with a small roller I-I.

The main frame I of the machine is served with a segmental plate J,suitablycalibrated and provided with an upturned iiange j, having a slotj.

K represents a guide in the form of a U or trough shaped member that ispivoted at onc end of said segmental plate, as at 1, and is served atits other end with a set-screw Zz', which passes through the slot y" andserves to secure the guide in any position to which it may be adjusted.It will be understood that upon the return of the carriage the lower endof the lever E enters the guide K and following the angle to which thesame is adjusted causes the platen to be rotated more or less accordingto the degree of spacing that is desired.

It will be obvious to those skilled in the art to which the inventionrelates that modificaj tions may be made in details Without departingfrom the spirit and scope of the same.n

Hence I do not limit myself to the precise construction and arrangementof parts illustrated in the accompanying drawings and hercinabovereferred to; but,

Having described the nature and objects of the invention, what I claimas new, and desire to secure by Letters Patent. is-

The combination of the main frame of the machine, thc paper-cylindercarriage, the paper -cylinder, its ratchet-wheel, a doublearmed levermounted in relation to the papercylinder whereof one arm is providedwith a pawl which engages said ratchet-wheel, and whereof the other armcarries a friction-roller, a plate secured to the main frame having aslotted segmental fiange, a longitudinallyranging trough-shaped guidefor said roller pivoted to the main frame and adjustable laterally inrespect to the line of axis of the paper-cylinder, `and a set-screwpassing through the slot and engaging the guide to secure it in itsadjusted position, substantially as specified.

In testimony whereof I aliiX my signature in presence of two witnesses.'
